On the Friday ministerial circuit:

• Minister of State for Sport Bal Gosal will be in the crowd at Tim Horton's Field in Hamilton, which is slated to be the scene of an international exhibition soccer match between Canada and England — which is, as per the advisory, "a warm-up for the FIFA 2015 Women's World Cup."
• At half-time, Gosal and local MP Mike Wallace will launch the #HighFive campaign — a new UN-driven initiative to raise funds for maternal, newborn and child health in Haiti — by "high-fiving soccer stars and leading the crowd in breaking the world record for the most people giving high-fives at one time."
